I have a compact 318ti keeps cutting out on occasion, any gear any rpm. battery lights flashes for less than a second and engine cuts then back to life and drives well, then same issue.
The battery is new, alternator checked ok.
Unable to diagnose as no fault code reported.
BMW specialist unable to identify the issue. The cam sensors connectors have been cleaned etc still same issue. happens at least once to twice on a good run, either short or long distance, some days is perfect then next day same issue again, please help.
Please could you advise and support me guys to fix this issue.
